Dropdown elements have [Visuals]/Z-Index of non-1

[cfarrier]

Some elements of the Dropdown examples are using a [Visuals]/Z-Index values other than 1. This causes problems when attempting to place another UIBlock2D on the display layered above the dropdown -- the dropdown fields with a Z-Index greater than 1 will hover above the UIBlock2D that should be visibly above them.

Tested in 1.1.8.

I think it doesn't matter that the value is not 1, the problem is that they aren't uniform, and that the Z-Index doesn't respect the GameObject order in the Hierarchy. An object with a higher Z-Index will float above an object lower in the Hierarchy.

Would you be willing to share a screenshot so we can get a better sense of what you're running into?

What you're describing here is the intended behavior of Z-Index - it provides a way to adjust render order without having to restructure a hierarchy. You can find more information about controlling UIBlock render order in our documentation as well!

Here is my UI:

Here is my UI with a UIBlock2D child that overlaps and has 50% alpha, giving it a disabled look. This happens when a modal pops up above this window.

Here is the same UI, but with the Z-Index values not set to zero. Notice how the "Option A" text and the arrow are not affected by the disabled look.

Ah. Thank you for the screenshots. We'll make sure to do a pass on these prefabs before our next release and adjust the z-index where a non-zero value isn't needed. Thank you for bringing this to our attention!

In the meantime, fortunately you're able to change the z-index locally to work around the issue!
